What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and the variety of ecosystems.

Front

What are adaptations?

Back

Adaptations are traits or characteristics that enhance an organism's ability to survive and reproduce in its environment.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through the environment.

Front

What is the role of producers in a food web?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is the significance of keystone species?

Back

Keystone species are organisms that have a disproportionately large effect on their environment relative to their abundance, helping to maintain the structure of an ecosystem.

Front

What happens during primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption, leading to the gradual establishment of a biological community.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts in a barren environment without soil, while secondary succession occurs in areas where a disturbance has destroyed an existing community but soil remains.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is the energy pyramid?

Back

The energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level, with producers at the base.
